Pull Request Checklist:

• This PR addresses an already opened issue (for bug fixes / features)
  • This PR fixes issue PermissionError upon importing clisops.core in some Windows environments #320
• Tests for the changes have been added (for bug fixes / features)
• Documentation has been added / updated (for bug fixes / features)
• HISTORY.rst has been updated (with summary of main changes)
• I have added my relevant user information to AUTHORS.md

What kind of change does this PR introduce?:

• Uses platformdirs to set a default platform-dependent location in the event that one is not provided for local_weights_dir.
• platformdirs now handles the caching location for testing data.
• require_module now handles supported module version information.
• Fixed the version pinning and comparison code for xarray (2023.03 → 2023.3)

Does this PR introduce a breaking change?:

Yes. The default location hard-set in the roocs.ini configuration has been removed.

Additionally, the .clisops_testing_data folder can be removed from your $HOME folder. This is now saved to $HOME/.cache/clisops on *nix.

Other information:

On Linux, this looks like:

from clisops.core.regrid import CONFIG

CONFIG["clisops:grid_weights"]["local_weights_dir"]
>>>'/home/my_user/.local/share/clisops/weights_dir'

@Zeitsperre @sol1105 when using platformdirs could we skip the roocs.ini config for weights_dir?

[Zeitsperre]

@cehbrecht I suppose you technically could. I've set it up so that if the option is not provided, it'll use a cached location, but if you'd rather remove this option entirely, you should be able to work with locations provided uniquely by platformdirs.

That looks great, thank you.

In the regrid notebook of the documentation, I used the explicit path instead of the CONFIG settings. I will update that
https://clisops--323.org.readthedocs.build/en/323/notebooks/regrid.html#Local-weights-cache

In general I wonder, whether the ./binder/environment.yml and ./docs/environment.yml are too extensive. Should they only include packages additionally required with regards to the basic ./environment.yml?
